Looking for Schematic for Braun PQ20
Hello I am looking for a schematic for Braun PQ 20.
I have a problem with this amplifier. http://ampguts.realmofexcursion.com/ads_PQ20/ http://img1.abload.de/img/braunpq20o1m4.jpg The connector who is in red underline is the problem. When he is connect the amplifier doesn´t work. If it is disconnect the amplifier goes on because the measurement shows 0,73A. The Transistor in the power amplifier (2SC 3281 and 2SA 1302 has got -30V and + 30V) Thank you for help. Regards Jörg |
